摘　　要：为了确保光伏组件垫片接地相比导线接地的成本优势具有实际意义,文章从接地电阻及导体电阻的概念出发,提出了一种特殊接地垫片。然后计算论述了组件通过导线接地和特殊垫片接地的异同及材料选择,并结合工程实例设计了两种接地方式的比较试验。通过试验结果验证了光伏组件通过特殊垫片的接地效果相近,得出了组件通过特殊垫片接地可以被应用于光伏发电项目的结论。In order to ensure the cost advantage of photovoltaic module gasket grounding compared with conductor grounding,a special grounding gasket is proposed based on the concepts of grounding resistance and conductor resistance.Then,the similarities and differences and material selection of component grounding through conductor and special gasket are calculated and discussed,and the comparative test of two grounding methods is designed combined with engineering examples.Through the test results,it is verified that the grounding effect of photovoltaic modules through special gaskets is similar,and it is concluded that the grounding of modules through special gaskets can be applied to photovoltaic power projects.
